CROSS REFERENCE TO RELATED APPLICATIONS

This application is the continuation of the U.S. patent application Ser. No. 17/219,921, filed on Apr. 1, 2021, which claims the priority benefit of Chinese Patent Application No. 202010257862.8, filed on Apr. 3, 2020, the full disclosure of which is incorporated herein by reference.

BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a scheme and device of multicarrier transmission in a wireless communication system in wireless communications.

Related Art

Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 plenary to standardize the NR.

Enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC) are three major scenarios of application of the NR technology. And multicarrier (including Carrier Aggregation (CA) and Dual Connectivity (DC)) is an effective technical means of fulfilling eMBB and URLLC demands.

SUMMARY

In the multicarrier communications, such as CA, Cross Carrier Scheduling is supported. And in order to meet requirements of URLLC, a UE can monitor a physical downlink control channel (PDCCH) Candidate based on Span. A combination of CA and Span-based scheduling can maximize the flexibility of network scheduling and configuration and optimize the entire system's performance.

To address the issue of multicarrier technology application in URLLC scenario, the present disclosure provides a solution. It should be noted that though the present disclosure only took the multicarrier and URLLC as a typical or exemplary scenario in the statement above, it is also applicable to other scenarios confronting the same difficulty, including other multicarrier transmissions or multi-channel transmissions, or other networks having specific demands on data scheduling, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios, including but not limited to multicarrier and URLLC scenarios, contributes to the reduction of hardcore complexity and costs. If no conflict is incurred, embodiments in the first node in the present disclosure and the characteristics of the embodiments are also applicable to a second node, and vice versa. Particularly, for interpretations of the terminology, nouns, functions and variants (unless otherwise specified) in the present disclosure, refer to definitions given in TS36 series, TS38 series and TS37 series of 3GPP specifications.

FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a control plane 300 between a first communication node (UE or gNB) and a second communication node (gNB or UE) is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer which performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present disclosure. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between the first communication node and the second communication node, or between two UEs via the PHY 301. The L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second communication nodes. The PDCP sublayer 304 provides varied radio bearers and multiplexing between logical channels, and also provides securing by packet encryption, as well as support for handover of a first communication node between second communication nodes. The RLC sublayer 303 provides higher-layer packet segmentation and reassembling, retransmission of a lost packet, and also packet reordering so as to compensate for disordered reception caused by Hybrid Automatic Repeat Request (HARQ). The MAC sublayer 302 provides multiplexing of a logical channel and a transport channel. The MAC sublayer 302 is also responsible for allocating between first communication nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer 302 is also in charge of HARQ operation. In the control plane 300, The RRC sublayer 306 in the L3 layer is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the second node and the first node. The radio protocol architecture in the user plane 350 comprises the L1 layer and the L2 layer. In the user plane 350, the radio protocol architecture used for the first node and the second node in a PHY layer 351, a PDCP sublayer 354 of the L2 layer 355, an RLC sublayer 353 of the L2 layer 355 and a MAC sublayer 352 of the L2 layer 355 is almost the same as the radio protocol architecture used for corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression used for higher-layer packet to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also comprises a Service Data Adaptation Protocol (SDAP) sublayer 356, which is in charge of the mapping between QoS streams and a Data Radio Bearer (DRB), so as to support diversity of traffics. Although not described in FIG. 3, the first node may comprise several higher layers above the L2 355, such as a network layer (i.e., IP layer) terminated at a P-GW 213 of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.).

The second node (410) can comprise a controller/processor 440, a memory 430, a receiving processor 412, a transmitter/receiver 416 and a transmitting processor 415, the transmitter/receiver 416 comprising an antenna 420.

In a Downlink (DL) transmission, a higher layer packet, such as higher-layer information contained in a first information block, a fourth information block and a fifth information block of the present disclosure is provided to the controller/processor 440. The controller/processor 440 implements the functionality of the L2 layer and layers above. In the DL, the controller/processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between a logical channel and a transport channel and radio resource allocation of the first node 450 based on various priorities. The controller/processor 440 is also in charge of HARQ operation, a retransmission of a lost packet and a signaling to the first node 450, for instance, the higher-layer information contained in a first information block, a fourth information block and a fifth information block of the present disclosure is generated in the controller/processor 440. The transmitting processor 415 performs various signal processing functions used for the L1 layer (i.e., PHY), such as coding, interleaving, scrambling, modulation and power control/allocation, precoding and physical layer control signaling generation. For example, the generation of physical layer signals of a first information block, a fourth information block and a fifth information block of the present disclosure is completed in the transmitting processor 415. When there is at least one among the M1 control channel candidates in the present disclosure being used for transmitting a control signaling, the generation of the control signaling transmitted is completed in the transmitting processor 415. Modulation symbols generated are divided into parallel streams and each stream is mapped onto a corresponding multicarrier subcarrier and/or multicarrier symbol, and is then mapped by the transmitting processor 415 to the antenna 420 via the transmitter 416 and transmitted in the form of a radio frequency signal. At the receiver side, each receiver 456 recovers baseband information modulation onto a radio frequency carrier and provides the baseband information to the receiving processor 452. The receiving processor 452 provides various signal receiving processing functions of the L1. The functions include receiving physical layer signals of the first information block, the fourth information block and the fifth information block in the present disclosure and monitoring the M1 control channel candidates in the present disclosure, as well as modulating based on each modulation scheme (e.g., BPSK,) through multicarrier symbols in the multicarrier symbol streams, and also de-scrambling, decoding and de-interleaving to recover data or a control signal transmitted by the second node 410 on a physical channel, and then provides the data and control signal to the controller/processor 490. The controller/processor 490 is in charge of the L2 and above layers. The controller/processor 490 interprets the first information block, the fourth information block and the fifth information block. And the controller/processor is associated with the memory 480 that stores program codes and data. the memory 480 can be called a computer readable medium.

In an Uplink (UL) transmission, the memory 480 is configured to provide higher-layer data to the controller/processor 490. The memory 480 represents the L2 and protocol layers above the L2. The controller/processor 490 provides header compression, encryption, packet segmentation and reordering, as well as multiplexing between a logical channel and a transport channel based on radio resources allocation of the second node 410, so as to implement the L2 protocols used for the user plane and the control plane. The controller/processor 490 is also responsible for HARQ operation, retransmission of a lost packet, and a signaling to the second node 410. The second information block and the third information block in the present disclosure are generated in the controller/processor 490. The transmitting processor 455 performs various signal transmitting processing functions used for the L1 (that is, PHY), and physical layer signals of the second information block and the third information block are generated by the transmitting processor 455. Signal transmitting processing functions include sequence generation (for signals generated by a sequence), coding and interleaving to ensure Forward Error Correction (FEC) at the UE 450 and modulation on baseband signals (for signals generated by a bit block) based on various modulation schemes. Signals generated by a sequence or modulation symbols are later divided into parallel streams and each is mapped to a corresponding multicarrier subcarrier and/or a multicarrier symbol, and then is mapped by the transmitting processor 455 to the antenna 460 via the transmitter 456 to be transmitted in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal via a corresponding antenna 420. Each receiver 416 recovers baseband information modulated on a radio frequency carrier and provides the baseband information to the receiving processor 412. The receiving processor 412 provides various signal receiving processing functions for the L1, including receiving a physical layer signal carrying the second information block and the third information block of the present disclosure. The functions also include acquiring a multicarrier symbol stream, performing demodulation of multicarrier symbols comprised in the multicarrier symbol stream related to sequence-unpacking or based on modulation schemes (such as BPSK, QPSK), decoding and de-interleaving of the demodulated symbols to recover data and/or a control signal originally transmitted by the first node 450 on a physical channel. Afterwards, the data and/or control signal is provided to the controller/processor 440. The controller/processor 440 implements the L2 functionality, including reading the second information block and the third information block in the present disclosure. The controller/processor can be associated with the buffer 430 that stores program codes and data. The buffer 430 can be called a computer readable medium.
